ok Maori is a free android app developed by shotgun.experiments that offers a quick and efficient way to learn and build Maori vocabulary. The app comes with over 2,000 Maori words and introduces the user to a new word every day. It is a perfect resource for anyone looking to increase their Maori vocabulary steadily and at their own pace.

The app uses a spaced repetition system (SRS) to test the user's knowledge of the words they have learned. This scientifically proven method optimizes memorization and retention of learnt vocabulary. In addition to its vocabulary building feature, the app also serves as a simple and straightforward reference English dictionary with an inbuilt search function.
